The Briggs & Stratton 691968 is a genuine OEM governor and oil slinger assembly designed to restore correct oil distribution and governor linkage function on compatible small engines.

If your lawn mower, generator, or other outdoor power equipment is showing oil leakage around the crankshaft area or uneven engine speed, replacing worn components with the exact Briggs & Stratton part can help return reliable performance.

How does this part affect oil distribution and engine longevity?

The oil slinger portion throws a controlled film of oil onto bearings and seals at the crankshaft, helping reduce wear from metal-to-metal contact. Installing the correct OEM slinger preserves the intended oil pathway and tolerances engineered by Briggs & Stratton.

• Restores original oil throw pattern to protect crank bearings
• Prevents excess oil pooling that can foul seals or breathers
• Maintains factory clearances for consistent lubrication

Will this governor assembly fix erratic engine speed or throttle problems?

The governor component maintains engine speed by connecting to the carburetor throttle linkage; replacing a worn governor helps the engine respond correctly to load changes. If the existing governor is damaged or the linkage is loose, a new OEM unit brings back intended mechanical control.

• Replaces worn or bent linkage to stabilize RPM under load
• Ensures correct fit with existing throttle components for precise control
• Works with the engine’s original governor springs and settings

Is this an exact match for parts listed as 490815 or 391764?

Yes — the 691968 is the genuine Briggs & Stratton part that supersedes and replaces the older 490815 and 391764 numbers. Using the updated OEM part ensures compatibility without the need for machining or modification.

• Direct replacement for 490815 and 391764 — no adapters required
• Manufactured to original dimensions and material specifications
• Tested to meet Briggs & Stratton quality and emission-related fit standards

How easy is installation and what tools will I need?

Installation is straightforward for anyone comfortable with small engine repairs: remove the engine cover, detach the old governor/oil slinger, and press or bolt in the new unit per service manual guidance. Typical tools include a socket set, snap-ring pliers if applicable, and a torque wrench to meet factory specs.

• Simple swap-in for mechanics familiar with Briggs & Stratton small engines
• Minimal disassembly: crankcase access and linkage removal are usually sufficient
• Follow the engine service manual for torque and lubrication steps
